K-pop (Korean: 가요, Gayo) (an abbreviation of Korean pop or Korean popular music) is a musical genre consisting of pop, dance, electropop, hip hop, rock, R&B, electronic music originating in South Korea. In addition to music, K-pop has grown into a popular subculture among teenagers and young adults around the world, resulting in widespread interest in the fashion and style of Korean idol groups and singers. Through the presence of Facebook fan pages, availability on iTunes, Twitter profiles, and music videos on YouTube, the ability of K-pop to reach a previously inaccessible audience via the Internet is driving a change in the exposure and popularity of the genre.[12] South Korean popular culture is today serving as a major driver of youth culture all across the Pacific Rim, with special reference to China, Hong Kong, Japan, Philippines, Taiwan and Vietnam.
